Answer:
The missing volume of gas is 6 liters
Step-by-step explanation:
The following data points represent the volume of gas in each race car driver's tank (in liters):
4,5, 13, ?
Let the missing value be x
Data : 4,5,13,x



28=22+x
28-22=x
6=x
Hence The missing volume of gas is 6 liters
Turn the fractions into decimals.
27/7 =3.85
31/8 =3.87
The in between number is 3.86
The phase shift is the value of the angle when the variable
in the angle is zero.
The angle in the sin function in this equation is (pi X + 2).
When the variable 'X' is zero, the angle is 2 .
So the phase shift of this sin function is 2 (of whatever
the unit of the angle is ... 2 degrees, 2 radians, etc.)
396,000
because 5 goes up and anything lower than five stays the same
